Current situation and objetives

In colombia

  • Air quality is a priority for local governments
  • High impact on population and resonance on media
  • Limited budget and technical capacity of local authorities
  • The academia ought to contribute

Our purpose: simplify and automate

  • Define repeatable and flexible data analyses
  • Develop tools for automating processes
  • Relay on open source

Application case: Bogotá

  • Data Source: RMCAB 1998-2016
    • PM10 and PM2.5

  • Data cleaning based on rules

  • Implementation with R
    • Web based
    • Intuitive Visualizations
